To Vall 't0/21cm itma/ concern:

Be 1t known that we, WALTER- TANNER Vand CURT HUNZIKER, citizens of the. Swiss Confederation7 Aresiding' at'Zurich. Switzerland, havevinvented certain new and useful Improvementsl in Sausage-Tying Machines, of which the following is a specification.

This invention relates to a macchine for tying sausages which permits theV use of metal wire, e. g. aluminum 'wire whereby the tying can be done with greater speed,

hitherto. y y

According to this `invention a device for .'unwinding the wire, asdevice for bending the wire and piressingfand cutting means are arranged onone frame, all these parts being connected with al driving shaft. The parts are arranged and constructed in such a manner that the corresponding operations are successively effected when the driving shaft revolves. n f

In order that the invention may be clearly understood, we will proceed to describe the same'vwith reference tothe accompanying drawing, wherein F ig. 1 is a front elevation and Fig. 2 a side elevationpartly in section.

Infbearings 2 of the frame 1 the .driving shaft. 3 is mounted. A connecting rod 5 hingedly* connectedwith the crank 4 of shaft 3 is hingedly connected at its lower end b-y means of bolt 6 with a two-armed lever 7. The lever is fulcrumed at 9 and its front end is enlarged to form a pedal.

The axle 9 is mounted inV brackets 10 cast inone piece withthe frame 1.

Upon a bracket 12 at the upper end of the frame 1 standards 11 are arranged in which a spool 13 is mounted on .which thel wire is wound. The wire 14 consists of soft, not rusting metal, e. g. aluminium. A heavy roller 40 is arranged above the wire spool, the ends of the axle 15 of said roller engaging with vertical slots 16 of the standards 11. Upon one of the ends of the axle of the spool 13 an eccentric disk 16 is keyed which is connected by a rod 17 with an eccentric 18 of the` driving shaft 3. When the shaft 3 rotates an intermittent revolving motion is thus communicated by the parts 16, 17, 18 to the spool 13 so that the wire 14 wound upon the same is intermittently onwound.

r1`he inclined front face of the bracket 12 has a semi-circular indentation 19 which is designed to bend the wire 14 properly before keyed upon the driving shaft 3.

' closed and opened.

I tying is effected. ver this indentation 19- aV pulley 20 is adjustably mounted .in a slot 271v of abracket` 22. The axle of said pulley .20 is connected with the upper end of the connecting rod 23 whose lower end termi- LA transverse channel 25serves for the reception of the sausage body tol be tied. This channel 25 isseparated at the middle by a gap in which scissors are arranged. These scissors serve for compressing the Vbody of the sausage. the scissors are mountedon a pivot pin 23 whichr is located in an arm 29 ofthe bracket 12. A rod 30 h-ingedly connected with the lower end of the arm 26 of the scissors is iiXed with its other end to an eccentric 31 `To the lower end of the othershank 27 of the scissors a rod 33 is hinged by meas `of a bolt 32, the other end of said rod `33 being con- The arms 26V, 271 which formf nates Vin an eccentric 24 keyed upon the driv- Y.

nected with an eccentric 34 keyed upon the i driving shaft 3. The pivot bolt engages with ak guide slot 35 ofthe support 36 fixed by means of screws 37 tothe frame 1. When the driving shaft 3 rotates 'the scissors formed by the arms 26, y2T-are alternately Theclosing arms compress thesausage body and at the same time the wire whereby the sausage is tied;

The arms 26 and 27' carry further cutter blades 38- designedto `cut=the wire 14` after the tying of the sausage. f f

The'scissors, the Vbending device and the wire spool work togetherin such a manv`ner `that a ycontinuousworking of the machine is ensured. The driving shaft 3 could be driven by aV motorv instead of being driven by a pedal lever as described.

We claim z- 1. An improved sausage tying machine comprising in combination with a frame a driving shaft revolubly mounted in said frame, a wire spool at the upper end of said frame9 a device for bending the wire, a transverse channel for the sausage body, scissors for compressing the sausage body and the bent wire and for cutting ofi the 'tied wire and means for operating said 'spool and said scissors intermittently from said driving shaft.

2. An improved sausage tying machine Ling shaft to which the other endof the said comprising in combination with a frame a driving shaft revolubly mounted in said iframe, a standard at the upper end of the frame having vertical guide slots, a wire spool revolubly mounted in said standard;

ya heavy roller above said spool movably mounted with its journals in said vertical .slots of the standard, a` connecting `rod hingedly connected with one of the ends of the wire spool, an eccentric upon said drivconnecting rod is fixed, a device for bending the wire, a transverse channel foiythe sausage` body, scissors for" compressing the sausage body and the ybent wire and for `cutting ofi' theV tied wire, and means for operating said spool and said scissors intermittently from .said'driving shaft.

3. An 4improved sausage tying machine comprising in combination with a frame a driving shaft revolubly mounted in said `frame, a standard at the upper end of the frame 'having vertical guide slots, a wire rso spool revolubly mounted in said standard,

a heavy roller'above said spool niovably mounted with it-s journals in said vertical slots of `the standard, a connecting rod hingedly connected with one of the ends of the wire spool, an eccentric uponsaid driving shaft to which the other end of said connecting rod is fixedja se1ni-circularindentation in the front face of the frame7 slotted arms pivotally mounted with their lower ends upon said frame,` a roller mountedV in saidV slotted arms so that one end of its axle projects. laterally from the corresponding arm, a connecting rod hinged toy said projecting end of the aXle of the roller, an

eccentric keyed upon said driving shaft to which the lower end of said connecting rod .is attached so that said rollerV is inter mittently pressed into said indentation to bend the wire, `a transverse channel for the sausage tbody, scissorsl for compressingthe Y sausage body and the bentv wire and for cutting off the tied wire, and means for operating said spool and said scissors inter- 'mittentlyl from` said driving shaft.
